Application iilcd August 20,1903. Serial No. 170,166.

,To all whom it ntf/,7] concern:

Be it known that l', HARRY lRwIN derniers, residing atTnscaloosa, in the county o'l' rlnscaloosa and State of l-tlabaina, have invented a new and Improved 'lrolley-I-lead, oi which the following is a specilieation.

lli/ly invention relates to the class of trolleyheads in which means are provided l'or preventing the trolley-wire leaving the trolley; and the invention primarily seeks to provide a device of this character oi' a very simple and ellicient nature which will readily and eiiectively serve its intended purposes.

Primarily the invention consists in a main trolley-wheel adapted for free movement in the snpporting-frame and supplemental auxiliary wheels or linderfor bringing the trolleywire inte proper alinement with the main or trolley wheel, the said trolley-wheel being so arranged as to liit the wire out of engagement with the iinders when the said wire is in engagement with the t1olleywlieel.

With other objects in View, which will hereinafter be apparent, the invention consists in the novel construction and combination ot parts, all oi which will be lirst described in detail and then speeilically pointed ont in the appended claims, reference being had to the accompanying drawings, in which- Figure l is a perspective view of my invention as applied iior use. Fig. 2 is a side elevation thereof. Fig. is a top plan view thereof. Fig. 4t is a cross-section on the line 4C ol. Fig. 2. Fig. 5 is a cross-section on the line 5 5 of Fig. E2. Fig. 6 is a similar view on the line 6 6 or' Fig. 2. Fig. 7 is a detail side elevation of a slightly-modilied form of my invention. Fig. 8 is a cross-section on the line 8 8 of Fig. 7'. Fig. 9 is a detail view of one of the trolley-wheels detached. Fig. 10 is a similar View of one of the lnder-wheels detached.

lteiierring now to the aecoml'ianying drawings, in which like numerals and letters oil' reierenee indicate like parts in all the figures, il designates a trolley-pole, to the upper end of which my invention is applied, and 2 desighates the trolley'wire, the pole and wire being el" any approved construction, since they per se `form no part of my invention.

lhe trolley-head (designated generally by A.) consists of a casing having side walls a and a central space a.' of sniiicient width to permit the tree rotation ot the trolley-wheel B, which in my invention is capable ol" a slight np-anddown movementin a vertical plane for a pnrpose presently to appear. The side walls a oi' the casing have slots a disposed at an angle to the vertical, and the said slots a terminate at their upper ends in enlarged circular portions e, as clearly shown in Fig. 2.

The trolley-wheel l has a shaft 7) of a diameter to loosely lit the slotways a, and the said shaft I) has eogs 7) at each end which mesh with the rack members C ot the casing-walls l and which rack members C are arranged parallel with the slotways ai and run Yfrom the lower end to the enlarged circular portion a3 at the upper end oi the slotways a.

D designates bracket members secured te the side walls of the casing, and the said bracket members have right-angled bearing-spindles Z to receive the lieder-wheels E, which consist of conically shaped members having spiral grooves e in their periphery, which have a liange e' at the base o'l the cone, while the small end ci ol the linder-wheels F play in ent-away portions a" in the said walls t and have their inner ends flushed with the inner surface ol" the sidewalls a3, as shown in Fig. 3.

The trolley-head A. may be attached in any approved manner to the trolley-pole l; but l preferably lorm the said head with an integral rod portion adapted to slip into the hollow end of the tubular trolley-pole l, and while .lf pre'ler to form the head A oig separate parts melted together, yet, if :t'onnd desirable, l may form the iframe with a single casting. Again, l may'dispense with the rack members U, Yfastened to the casing-wall, and form the said rack as an integral part of the slotways ai, as shown in Figs. 7 and 8. by reierence to which it will be seen that the slot- Ways are 'formed with slnooth portions a7 and rack portions U., and when this form ol my invention is used the trolley-wheel shaft Z) is Formed with a smooth portion and a pinion portion between said smooth portion 3f and the trolleyavheel l, so to cooperate with the said smooth and rack portion ol the slotiivays ai.

bio feras described the manner in which my invention operates will be best explained as follows: Assuming the parts to be in the position shown in Fig. l, if the trolley-Wire should leave the trolley-Wheel the said trolley- Wheel will drop down into the casing with its shaft at the lowermost end of the slotvvays a2, and the trolley-Wire will come into engagement with the finder-wheels, which by reason of their shape and by reason of their spirallyarranged grooves will carry the Wire toward the casing and drop it into the open portion a at the top, when the Wirewill again engage the trolley-Wheel, causing it to rotate, and asA the pinions on the trolley-Wheel shaft are in engagement With the racks on the casing the said trolley-Wheel will rise until its shaft engages the enlarged portion of the slotway at the upper end thereof, when the pinions will have left the racks, and the wheel may then turn freely. In rising the trolley-Wheel leaves the trolley-Wire above the finder-Wheels, so they will not interfere with the said Wire When the parts are in their normal operative position, as shown in Fig. l. It should be understood thaty as the trolley-Wheel and the trolley- Wire become disengaged from each other the slightest jar of the trolley-head will be sufficient to move the Wheel B into engagement With the rack-teeth C.

From the foregoing description it Will be seen that I have provided a simple and easilyoperated trolley-head which Will effectively maintain the trolley-wheel on the Wire at all times, and by constructing the finder-Wheels as shown and described and by beveling the front edge al of the casing-head, as shown in Figs. l and 2, should the trolley-head become entirely disengaged from the trolley-Wire any cross-Wires or hangers with which the head might come in contact will not be injured in any way, as the head Will readily pass under the said cross-Wires or hangers.

From the foregoing description, taken in connection With the accompanying drawings, it is thought the advantages and complete operation of my invention will be readily understood by those skilled in the art to Which it appertains.

Having thus described my invention, What I claim, and desire to secure by Letters Patent, is

l. In a trolley-head, comprising in combination With a trolley-Wheel, of supplemental and finder Wheels arranged in advance of the trolley-Wheel and adapted to be engaged by the trolley-Wire at predetermined times, said trolley-Wheel being arranged for up-and-doivn movement in a vertical plane at predetermined times.
